Even if you can add rules and ActionScript, its still really clear and self-explaining for beginners.
AND: the support is amazing! Its not like other support teams that try to get rid of you as quick as possible. They REALLY do everything to solve the problem and they attach great importance to find the issue, and not just adding some stupid patch.
Now they changed many many features that were perfect before to be way more complicated now... eg the vat system, price showing (still dont get it), checkout-site.
Sorry, but I think you're going to the complete wrong direction.
I have a lot of coding knowledge and VM knowledge, but I'm too tired to solve all those issues and questions I have with the new VM2.
I wish, they had just improved the features from VM1 and not turned everything upside down.
Thank you for sharing your insight with us, VAT is a simple matter of adding a tax. If you are referring to the way tax is displayed on the products page, this can easily be adjusted with radio buttons in the administrator/index.php?option=com_virtuemart&view=config >> configuration > checkout.
Hope this helps, if not, please head over to the VirtueMart forum for help.
Thanks a lot!
